Quick Solution

This number series does not follow a simple arithmetic pattern (like adding or subtracting a constant value). The trick to this puzzle is to reverse the digits of each number to reveal a hidden, simpler sequence.

1. Reverse the Digits of Each Number

Let's take each number in the series and write it with its digits reversed:

• 61 becomes 16
• 52 becomes 25
• 63 becomes 36
• 94 becomes 49

This gives us a new, hidden sequence: 16, 25, 36, 49, ...

2. Identify the Hidden Pattern

This new sequence is a simple and recognizable pattern of consecutive perfect squares:

4²,    5²,    6²,    7²,    ...

The next number in this pattern of squares would naturally be 8², which is 64.

3. Find the Next Number in the Original Series

- The next number in our hidden sequence is 64.
- To find the corresponding number in the original series, we must reverse the digits of 64 back to their original format.

Reversing 64 gives us 46.

Final Answer: The number that comes next in the sequence is 46.
